UIC engineers have introduced a groundbreaking method for producing hydrogen gas using solar power and agricultural waste, drastically reducing energy consumption and enabling net-zero greenhouse emissions.
Engineers from the University of Illinois Chicago have developed a novel method to produce hydrogen gas from water using solely solar power and agricultural byproducts like manure and husks. This technique slashes the energy required to extract hydrogen from water by 600%, paving the way for more sustainable and environmentally friendly chemical manufacturing.
Hydrogen-based fuels are one of the most promising sources of clean energy. But producing pure hydrogen gas is an energy-intensive process that often requires coal or natural gas and large amounts of electricity.

I want to like solar. but it is just not the best option in most places it is being forced.
If renewables are being used to generate more direct forms of energy, then their innate unreliability because they are dependent upon nature is much reduced.
It doesn’t matter, if over the course of a month, that solar was down two days per week, because we don’t see that directly. The hydrogen it generated is what we see directly.
“This technique slashes the energy required to extract hydrogen from water by 600%”
So does that mean it not only extracts hydrogen at no energy cost, but it also GENERATES 5 TIMES as much energy in the other direction (meaning that it provides energy in the process, rather than consumes it), or are we simply dealing with another liberal arts major writing the story?
It uses the same power as a AA battery, according to the article.
The other nice thing is that the carbon slurry that is left over can be used to create graphene.
The energy requirements were low enough that the researchers could power the reaction with one standard silicon solar cell generating roughly 15 milliamps of current at 0.5 volts. That’s less than the amount of power produced by an AA battery.
“It’s very efficient, with almost 35% conversion of the biochar and solar energy into hydrogen,” said Rohit Chauhan, a co-author and postdoctoral scholar in Singh’s lab. “These are world record numbers; it’s the highest anyone has demonstrated.”
Does this mean that raising livestock is okay now?
It will now be encouraged.
The cost of power that is equivalent to a AA battery is about $0.25/year. So, that seems very cost effective.

Yes use it on DC.
Wouldnt methane gas be easier and more naturally ocurring?
Until then I am skeptical of most claims. This is what happens to people when they are constantly barraged with lies.
Unfortunately many lies have their origins in the University setting and are the product of scientists & engineers with an agenda, but no real plan.
So forgive me for being a skeptic, because everything surrounding green energy based efforts have proven themselves to be BS, so that now the hydrogen fix just becomes the latest salvo as far as I am concerned.
Well then, the good news is that Washington DC will be energy independent for a millennium.
I understand that. I’m taking, if this is true stance. Even if they were telling the truth, it doesn’t mean that it can be scaled up to industrial size so easily.
Reactions in labs may be completely ineffective when scaled up to mile squared vats.
AFIC the one MOST responsible for (9/11) is Jamie Gorelick. As Deputy AG under Obama she erected a wall between the FBI and CIA regarding sharing of information, overseeing specific cases, etc. So what the CIA learned about arabs taking flight lessons here in the US didn’t/couldn’t get to the FBI, etc.
To compound absurdity over disaster she was one of the principals on the 9/11 commission. She was then rewarded with a position to head up Fannie Mae as Vice Chairman where she later received MILLIONS in bonuses
Sounds promising but a long way from doable...they mentioned using sulfuric acid to make the biochar. Not sure how much you’d need for something like a waste lagoon...
Would you truck the waste to a converter or set up next to the waste lagoon with,say, a trailer mounted plant and separate collection vessels for they hydrogen and CO2...
Be interesting to see it happen.
If all these technologies can come together in a synchronistic way, there might not be much in the way of waste at all.
Rice University has developed a technology, at the lab level, where they can jolt/heat carbon sources in a flash. The garbage just breaks down to its element components and the carbon can be stripped of and be turned into graphene, while all you’d have left is metals and garbage like. All the gas in the garbage would be evaporated instantly.
Again, if everything works at the lab level can be supersized to industrial level.
Quit talking, start building, to start showing.
Electric cars are a terrible conception which actually does more harm to this globe and her environment, than do so-called fossil fuel (there is no evidence that oil is the byproduct of fossils).
That theory has been debated for decades.
Just because some biomarkers can be found in oil does not confirm fossils as the source. That could merely be the result of absorption by the oil.
To make a long story shorter, the whole climate change hysteria is a tool to acquire power.
The predictions that have been ongoing for decades also, have proven themselves to be false because not a single dire prediction has panned out. How many failures of dire predictions does it take for the realization that the claim is a lie, becomes more powerful than the claim that is consistently wrong?
